WebbIncluding the second A phase controls for the potential rival hypothesis of history that is a problem in a basic time-series design (i.e., in an A-B design). Basically, you are looking for the “fingerprint” of a stable baseline (during the first A phase), then a clear jump or change in level or slope (during the B phase), and then a clear reversal or return to the stable … WebbA simple interrupted time series design provides a reliable measure of the effect of the treatment because there are many observations both before and after the treatment.

WebbIn time series analysis, analysts record data points at consistent intervals over a set period of time rather than just recording the data points intermittently or randomly.

Webb30 nov. 2016 · According to Daniel T. Kaplan and Leon Glass (1995), there are two critical features of a time series that differentiate it from cross-sectional data-collection procedures: Repeated measurements of a given behavior are taken across time at equally spaced intervals.

Webbsufficiently long time series, the median time point of the preintervention period is a good choice of a pseudo-start period to maximize power to detect a significant jump (because the subsample will be evenly split on both sides). For shorter time series, a simple iterative process of testing each preintervention time period as the pseudo- Webbstudies that utilize basic interrupted time-series designs, the validity of these inferences can be questioned because a shift in the time series may be the result of something other than the treatment (e.g., an event that happened to occur around the time of the intervention; Shadish, Cook, & Campbell, 2002).
